I have a HUB5000_0 on an operational machine with (amongst other things) a 16x DAQ1301_0 digital input Phidget.
It uses existing channels for a mixture of SMC D-A93A(V) reed switches and ME-9101 spring switches. This all works very well. I have some free channels and would like to add 4 ME-9101 switches in series (probably using 1 of the free channels).
However, the total wire length is likely to be almost 10 metres. I know I could refit the whole machine to use the HUB5002_0 but this is no feasible at this time (I'm in Australia).
I'm thinking of a solid state relay. The input side for the relay would be a 12 VDC circuit connected to the 4 switches in series.
On the load side of the relay would be the DAQ1301_0 channel like with the other switches. The question is:
"Would this work or do I need a different solution? If so, what would that look like?"
Our machine is not pretty but I've attached an image for the curious.

I’ll leave your question for others to answer, but for your reference and others who might come across this thread, Phidgets are now available on Amazon Australia: Phidgets Store - Amazon Australia
I'm not sure what the solid state relay is for - you should just be able to hook up your switch circuit directly. DAQ1301_0 inputs are fully isolated from each other and can handle up to 30V.

The total wire length is approx 10 metres and series 1 have a limit of 5 metres... Or doesn't this apply?

Have you purchased from this store? I've noticed that most Amazon Aus stores are just an online store front and don't actually stock anything in Australia.
I generally order from https://www.iot-store.com.au/collections/phidgets which does carry some stock. Although, with most orders they still need to back order from Canada. However, they will place a specific order for you if you agree to pay the freight.
If a Phidget is listed on the Amazon Australia store, it means it's in stock locally. We've specifically stocked these items in Australia to help reduce shipping times and import costs for our Australian customers.

The 5 meter limit applies to the VINT cable between the VINT hub and the VINT device. I may have misunderstood - I though you were going to use 10m of wire for the switch circuit connected to the DAQ1301_0, not for relocating the the DAQ1301_0 further from the hub.
